A display device includes: a first organic layer; display elements over the first organic layer in correspondence with the pixels; an inorganic layer sealing the display elements and the first organic layer; a second organic layer on a part of the inorganic layer; and a touch electrode on a surface of the inorganic layer and a surface of the second organic layer. The first organic layer has a rift in the peripheral area to surround the display area. The inorganic layer includes a concave part over the rift, and extends from the display area to the peripheral area continuously. The second organic layer is on the concave part of the inorganic layer. The surface of the second organic layer on which a touch electrode is put is contiguous to and is surrounded by the surface of the inorganic layer on the concave part.

A switchable mirror system and method includes a laser imaging module including one or more lasers and one or more DMDs (Digital Micromirror Devices), and a switchable mirror component located in a path upstream from the DMD (or DMDs) to direct a laser from the DMD when there is pause in a printing operation facilitated by said laser imaging module. A non-mechanical and electronic switchable mirror is thus located in the laser path between an LDA (Laser Diode Array) and a DMD to divert energy out of the system and away from the DMD during periods of non-laser imaging without reducing or power down the laser system.

A metamaterial control device is provided for controlling electromagnetic radiation. The device uses a light-guide film (LGF), with the LGF being capable of receiving light emission along an edge. The device includes a substrate disposed on a non-edges surface of the LGF, electromagnetic cellular structures that are controllable, and an optically sensitive component within some or all cells. The substrate is composed of metamaterial and having an interface that corresponds to an extractor on the non-edge surface for scattering light therefrom. Alternatively, the substrate can constitute the LGF itself. The cell structure is disposed around the extractor. The optically sensitive component is disposed to cover the extractor. The component changes in response to receiving the light from the extractor and changes in response to intensity of the light.

A meta device includes a plurality of meta structures that spaced apart from each other and reflect at least a portion of incident light, a plurality of electrodes that are spaced apart from each other, and a controller configured to control a phase shift of reflected light using a voltage applied to the plurality of electrodes.

Nanoplatelet forms of metal hydroxide and metal oxide are provided, as well as methods for preparing same. The nanoplatelets are suitable for use as fire retardants and as agents for chemical or biological decontamination.
